Definitions

  • the invention relates to a method for producing a composite material.
  • the invention relates to an apparatus for producing a composite material.
  • components made of fiber-reinforced plastic are used.
  • Components made of fiber-reinforced plastic have the advantage of higher specific mechanical properties than metal components.
  • plastics can also be used in areas where metals would corrode.
  • EP 2 301 735 A2 shows a semifinished product and a semi-finished composite and manufacturing method for this semi-finished product.
  • This composite then forms a kind of "sheet metal" that can be reshaped like a metal sheet.
  • This semi-finished product has a relatively high tensile strength in the direction in which the fibers extend. In a direction transverse to the longitudinal extent of the fibers, the tensile strength is significantly lower. In order to increase the tensile strength, arranging several such semi-finished products one above the other, wherein the angular positions of the fibers differ from each other.
  • Another way to produce a semi-finished product with increased tensile strength in several directions is to produce a so-called multi-axial web.
  • EP 1 719 609 A2 shows a method and apparatus for producing a composite web based on at least two webs.
  • two webs are fed parallel to a positioning zone.
  • the two tracks lie next to each other.
  • Another web is fed at a right angle to the first two webs, however, segments must be cut from this web before reaching the positioning zone.
  • the length of these segments corresponds to the sum of the widths of the two webs.
  • the segments and the webs are then joined together to form a composite web that can be wound up on a roll.
  • US 2009/0301642 A1 shows a similar approach.
  • a first semifinished product web is fed transversely to a second semifinished product web.
  • the first semifinished sheet has reinforcing fibers which run parallel to the longitudinal direction of the semifinished sheet, ie enclose an angle of 0 °.
  • the semifinished sheet has fibers which also enclose an angle of 0 ° with the longitudinal direction of the semifinished sheet.
  • a multiaxial layer is created by stacking UD tracks at different angles (0 °, plus 60 °, minus 60 °).
  • US Pat. No. 4,875,959 describes a method and apparatus for making a tire. Be here Elements of a rim tape laid one on top of the other and connected together on a drum.
  • FR 1 362 190 A shows the production of sleeves for pneumatic bands of individual pieces, which are formed into a ring.
  • WO 2012/096696 A1 shows a composite material and a method and an apparatus for its production.
  • the composite is composed of modules, each of which has at least two layers of differently oriented fibers.
  • US 4,708,761 A describes a device for laminating prepreg materials. These materials are unwound from rolls arranged side by side. The prepreg materials are pulled onto a support table which is laterally movable so that this support table can be positioned in front of each roller. The webs that have been removed from the rolls are deposited on the support table and then laminated together. The webs are either single-layer webs with a fiber direction of 0 ° or multi-layer webs, in which one layer has a fiber direction of 0 ° and other layers different directions of fiber.
  • AT 397 062 B shows a method for the production of moldings from a plurality of oriented plastic films and a system for carrying out the method.
  • molded body made of a plurality of superposed and pressed together oriented plastic films.
  • the invention has for its object to facilitate the production of multiaxially reinforced materials.
  • the object is achieved by a method for producing a composite material having the features of claim 1.
  • the semi-finished sheets can be fed in each case in their longitudinal direction, comparatively little space is required. Also, the control of the supply of the webs can be made simple, because you do not have to make complicated conversions, in which the angle of supplied fibers or yarn sheets must be considered.
  • At least two semi-finished sheets have different predetermined angles. If you use more than two semi-finished sheets, of course, two of these semi-finished sheets can also have the same angle. However, the angles of at least two semifinished sheets differ so that increased tensile strength can be achieved in at least two directions.
  • the semifinished sheets are bonded together under the influence of temperature.
  • the application of an elevated temperature is usually easily possible.
  • the increase in temperature may, for example, soften the surface of at least one semifinished product web so that it becomes tacky and adheres to another semifinished product web.
  • a connection is made between two adjacent semifinished webs before another semifinished web is added. If, for example, a first semifinished product web and a second semifinished product web are stacked on top of each other, then these two semifinished product webs can be joined together before a third semifinished product web is laid onto the second semifinished product web. The third semifinished web is then joined to the second semifinished web before the fourth semifinished web is laid up and so on.
  • this has considerable advantages, because the heat must penetrate only one semifinished sheet.
  • connection aids are arranged in the intermediate spaces between the semifinished product webs.
  • the connection aids prepare the surfaces of the semifinished product webs such that they can be connected to the adjacent semifinished product webs.
  • the semifinished webs are wound off rollers whose axes of rotation are aligned parallel to one another. You can then arrange these roles in the longitudinal direction one behind the other. To produce the composite material, it is then only necessary to unwind or pull off the semifinished product webs from the rolls. In many cases, this does not even require a drive of the rollers. The control is kept relatively simple.
  • the semi-finished sheets are welded or glued together, for example.
  • the bonding can be accomplished by introducing an adhesive between the adjacent semi-finished sheets, which then connects the two adjacent semi-finished sheets together.
  • a solvent which dissolves the surface of at least one semifinished sheet so as to join the surface of the adjacent semifinished sheet.
  • the type of connection depends, of course, on the plastic or matrix material of the semifinished product webs used.
  • the semifinished sheets are joined together under pressure.
  • the pressure action can be used simultaneously to calibrate the composite.
  • the object is also achieved by a device for producing a composite material with the features of claim 7.
  • At least two of the semi-finished sheets have different predetermined angles.
  • Such a device can be used to produce a composite material which has at least two fiber layers with different angles to the longitudinal direction. Accordingly, this composite has increased tensile strength in the two directions of the fiber layers.
  • At least one output device has a supply roll.
  • the semifinished sheet can then be unwound from this supply roll. This facilitates stockpiling.
  • At least two dispensing devices each have a supply roll and the axes of the supply rolls are aligned parallel to each other. You can then arrange these roles in the longitudinal direction one behind the other or one above the other. For producing the composite material, it is then only necessary to unwind or strip the semifinished product webs from the supply rolls. A diversion is not essential.
  • connection device has a heat source.
  • the heat source may be used to increase the temperature of at least one semifinished sheet. Depending on the desired connection between adjacent semifinished sheets, the temperature can then be made so high that adjacent semi-finished sheets are welded together.
  • the connecting device has a dispenser for adhesive and / or solvent.
  • the adhesive may then be used to bond adjacent semi-finished webs together. If a solvent is used which solubilizes the surface of the semifinished sheet, then this solvent can be applied and the then dissolved surfaces joined together. Some adhesives also stick better when the opposite surface has been pretreated with a solvent. Some adhesives also stick better or faster when heat is applied.
  • a pressure device which presses at least two semifinished sheets for joining each other. Increased pressure usually leads to an improved adhesive bond.
  • the pressure device has at least one roller pair.
  • the roller pair then forms a nip through which the composite, i. the stack of at least two semi-finished sheets, is passed.
  • Fig. 1 shows in highly schematic form a semifinished product web 1, which has a symbolized by an arrow longitudinal direction 2 and a plurality of unidirectionally directed defined fibers 3.
  • the fibers 3 extend at a predetermined angle a to the longitudinal direction 2.
  • a supply sheet 4 is used.
  • the supply track 4 can be unwound, for example, from a supply roll 5.
  • a plurality of supply rolls 5 next to one another and, correspondingly, to pull off a plurality of supply sheets 4 at the same time.
  • the supply track 4 can also be generated online.
  • the supply track 4 can, if appropriate already in the form of segments, also be removed from a storage or magazine.
  • the web of a semi-finished product can be used as Vorratsbahn, the in EP 2 301 735 A2 is described.
  • the supply track 4 may comprise a plurality of unidirectionally directed defined fibers 6, which are arranged between two layers of thermoplastic material. Another structure is of course conceivable. However, the supply track 4 has a matrix of a plastic, which holds the fibers 6 in their unidirectionally directed orientation.
  • the supply track 4 has a main direction 7 marked by an arrow.
  • the main direction 7 is the "longitudinal direction" of the supply track 4.
  • the term “main direction” is used for differentiation purposes.
  • the fibers 6 are aligned in the direction of the main direction 7, ie they are parallel to the main direction 7, wherein the term “parallel” is not to be understood in the mathematically strict sense.
  • Fig. 1 How out Fig. 1 can be seen, 4 segments 8 are separated from the supply track. Each segment has two longitudinal edges 9, 10. These longitudinal edges are directed parallel to the main direction and thus parallel to the fibers 6. The longitudinal edges are at the predetermined angle a to the longitudinal direction of the second
  • a separator 11 is used to separate the segments 8. This separating device cuts through the supply track 4, for example with the aid of ultrasound, with a knife, with a pair of scissors, with a band knife or with a fall knife or a guillotine.
  • the separating device 11 generates a dividing line 12, which is directed parallel to the longitudinal direction 2.
  • the supply track 4 is fed at an angle a to the longitudinal direction 2.
  • the separating device 11 separates the segments 8 with a length of their longitudinal edges 9, 10, which corresponds to a width B of the semifinished product divided by the cosine of the angle ⁇ .
  • the longitudinal edges 9, 10 are therefore longer than the width B of the semifinished product web 1. However, they are just as large that the segments 8 can later be combined to form the semifinished product web having the desired width B.
  • the segments 8 can also be taken from a magazine or a store in which they have previously been stored.
  • the segments 8 are stored one after another on a conveyor, not shown, and conveyed in the longitudinal direction 2. As soon as enough space is available, the next segment 8 is deposited on the conveyor.
  • the representation in Fig. 1 Figure 8 shows the segment 8 separated from the semifinished sheet 1. This illustration was chosen to simplify the explanation. In fact, the segment is placed after the already finished semi-finished sheet 1.
  • the semifinished product web 1 itself forms the conveyor, i. by a train on the semifinished product 1 space for the next segment 8 is created.
  • connection of adjacent segments 8 at their longitudinal edges 9, 10 can be done in different ways.
  • the longitudinal edges 9, 10 may be placed abutting each other and welded together by the application of heat or ultrasound. It is also possible to use a band overlapping the longitudinal edges 9, 10, which band is formed from the same material as the matrix material of the supply track 4, and then weld or glue this band to the segments 8. It is also possible to use an adhesive tape or to bond the abutting longitudinal edges 9, 10 directly to one another. You can do this, for example use a hot glue. Adjacent segments 8 can also be overlapped in the region of their longitudinal edges and then melt together. For heat supply common sources, such as laser, hot air or infrared radiation are possible.
  • a connecting device 13 which can be guided in the direction of a double arrow 14 on the semifinished product web 1, ie over the two longitudinal edges 9, 10 of adjacent segments 8.
  • a pressure device 15 which in the direction of a double arrow 16 can be guided over the semifinished product web 1.
  • the connecting device 13 and the pressure device 15 can be operated separately or together. In the latter case, they can also be designed as a common assembly.
  • the connecting device 13 can be displaced during the joining of adjacent segments 8 in the longitudinal direction 2 when the transport device is moved continuously in order to convey the semifinished product web 1 continuously.
  • the connecting device 13 (the same applies, of course, for the pressure device 15) but can also be kept stationary in the longitudinal direction 2 when the conveyor is actuated in cycles.
  • the semifinished sheet 1 can be wound into a winding roll 18 to facilitate its handling.
  • Fig. 2 shows in highly schematic form a device 19 for producing a composite material 20.
  • the composite material 20 is formed in this case by five semi-finished sheets 1a-1e, which are unwound from five winding rolls 18a-18e. A different number of semi-finished sheets is of course possible.
  • the winding rolls 18a-18e have axes of rotation aligned parallel to each other, so that the individual semi-finished sheets la-le can also be fed parallel to one another.
  • the bonding can be effected, for example, by applying an adhesive to one or both semifinished product webs before the semifinished product webs are placed on one another. It is also possible to soften one or both semifinished sheets on their surfaces by heat or chemical means so that they will bond together after laying, optionally by applying pressure.
  • Heat may also be passed through a semifinished sheet after it has been brought into abutment with another semifinished sheet to effect welding. This heat application should be done before a another semi-finished sheet is applied, so that the heat must penetrate only a single semifinished sheet.
  • Fig. 2 shows the various possibilities for interconnecting semifinished product webs.
  • an adhesive applicator 21 is provided, with the adhesive is applied to the side of the semifinished sheet 1 b, which is brought to bear against the semifinished sheet 1 a.
  • a first intermediate product 22 of the composite material 20 which is composed of two semi-finished sheets 18a, 18b.

  • a further heating device 24 may be provided which heats the upper side of the intermediate product 22 facing the semifinished product web 1c in order to improve the adhesion or welding of the semifinished product web 1c to the intermediate product 22.
  • a welding device 25 is provided with which the heat necessary for welding can be introduced into the semifinished product web 1d. This heat penetrates this semi-finished sheet 1d and heats it such that it is welded to an intermediate product 26 composed of the semifinished product webs 1a, 1b, 1c.
  • the intermediate product 26 together with the semifinished product web 1d forms an intermediate product 27 which, together with the semifinished product web 1d, is passed through a nip formed between two pressure rollers 28, 29.
  • the pressure applied there optionally after applying an adhesive to the semifinished product web 1e or a corresponding preparation, connects the semifinished product web 1e with the intermediate product 27 in order to form the composite material 20.
  • connection types were listed here by way of example only. In many cases, it will be expedient to connect all semi-finished sheets 1a, 1b, 1c in the same way. If different connection types are selected, a different order of connection types is possible.
  • At least two of the five semi-finished sheets 1a-1e have different angles a between the unidirectionally directed ones Fibers 3 and the longitudinal direction 2. In many cases, it will be favorable to provide all five semifinished sheets 1a-1e with different angles a of the fibers.
  • the device 19 is relatively simple. You can in principle use several similar modules. Since these modules can be arranged one behind the other, relatively little space is required.
  • the composite material 20 can also be produced in such a way that the semifinished product sheets 1a-1e are gathered in a fan-shaped manner from the side, heating fields being provided in the spaces between the individual semifinished product sheets 1a, 1e which, for example, due to radiant heat or contact heat Heat surfaces of the semifinished sheets 1a-1e.
  • adhesive application devices may be provided in the interstices. In both cases, all the semi-finished sheets 1a-1e are simultaneously pressed against each other and thus joined to form the composite material 20.
